Within the paragraph:

" Jim always seems to score well on tests. How does he do it? Jim offers these tips for successful studying. The first step is to decide what to study. Find out what topics will be covered on the test. Next, organize your notes and other materials on these topics. Third, make study guides to use as memory aids. Your final step is to review your notes and study guides until you feel confident about taking the test." (from Becoming a Confident Reader, p.200)

"All organisms must insure that their offspring have a reasonable chance to survive and begin a new generation. Plants, however, face special challenges. Plants do not have nervous systems, and they are not able to run away from predators or pests. Because nearly all plants live in fixed positions, they must also manage to find mates without being able to move around. Therefore they have evolved strategies for dealing with these problems that are essentially passive. An important part of such strategies is a reproductive pattern enabling each individual to produce large numbers of offspring." (Levine and Miller, Biology, 1991)
